T 0 all whom it may concern: v

Be it known that I, RE E BRUNET, a 'citizen of Canada, residing at NewYork, in the county of New York and State of New York, have invented newand useful Improvements in Submarines of which the fol lowing is aspecification.

The present invention relates to submarines, and, more particularly, tosafety device for same, in the form of compartments in which the crewmay take refuge, in the event of accident to the craft. The safetycompartments are all provided with means of communication with theinterior of the submarine and also with the outside by means of suitablyoperated doors as hereinafter described.

The object of the present invention is to provide a simple yet efiicientmeans whereby the crew may make their exit from the craft in case ofemergency, a further object is to so construct the device so that itsoperation will be positive, and also comparatively inexpensive tomanufacture, another object is to provide means for preventing the waterpressure from forcing the crew against the walls of the safetycompartments,'other objects will be obvious from the followingdescription and the subjoined claims.

Referring to the accompanying drawings, in which similar referencecharacters refer to similar parts in the several figures :-Figure 1 is aplan view of a submarine showing my invention. Fig. 2 is a sectionalview on the line 22 of Fig. 1. Fig. 3 is an enlarged horizontal sectionof a portion of the submarine. Fig. 4: is a diagrammatic view showingthe mechanism and circuits for op erating the safety doors.

Referring to Fig. 1 I have shown two compartments 10 and 11communicating with the interior of the submarine by doors 12. Thesedoors may be held securely closed by suitable latches 13. On the outerwall of the submarine there are doors 1% which are normally held inclosed position by a suitable latch 15. At the rear end of each door issecured a rack 16. Pinions 17 are secured to the armature shafts of themotors 18. The circuits of the motors 18 are controlled by apole-changing switch 19, by means of which the current from the storagebattery 20-may be caused to flow in opposite directions therebyreversing the motors 18 when so desired.

In the walls of the compartments 10 and 11 I provide vent passages 21.Levers 22 pivoted at 23am provided with plugs 24 adapted to close thevent passages 21. The levers 22 are provided with toes 25 adapted tocoact with the lugs 26 integral with racks 16. l

The interior of the walls of the chambers 10 and 11 is provided with aplurality of bars 27 spaced away a short distance from the-inner wallsof said chambers similarly. The doors 12 are also provided with aplurality of bars 27.

From the foregoing it will be obvious that if this submarine becomesdisabled while submerged, the crew will be able to escape as willpresently be described. The door 12 may be opened and the crew may entereither one of the compartments 10 or 11, the

latch 13 on the door 12 may be so constructed that when the door isclosed it will automatica ly lock. The occupants of the safetycompartment may then un-lock the sea-doors let and operate the switch 19so as to put the motors 18 in circuit with storage batteries 20. Thiswill cause the pinions 17 to rotate in the directions of the arrowsshown in Fig. 4. These pinions in turn will draw back the racks 16 andthe doors 14 attached thereto. As the doors 14; gradually open, thewater will gradually flow into the compartments 10 and 11 and fill thesame. It will be obvious that if some safety means were not provided thegreat water pressure thus obtained would cause the occupants in thesafety compartments to be forced against the walls of the compartment,but by providing the bars 27 it will be readily seen that the crew willbe forced against these bars which being spaced away from the walls willpermit the water to flow all around said bars and therefore equalize thepressure on the said occupants of the compartments', hence they would beable by their own physical efforts to free themselves from thecompartments. It being understood that the occupants before entering thecompartments may have been equipped with divers or other suitabledevices for under water travel.

The operation of the air vents will now be described: As the doors 14move back, the lugs 26 will engage the toes 25 of the levers 22 andcause the air vents 21 to close and thereby prevent the entrance ofwater into bars spaced a short distance away from'said walls, means forcommunicating with the interior of the submarine and said safetycompartments, sliding doors for said safety Copies of this patent may beobtained for compartments communicating with the out side, means foroperating said latter'doors, means for controlling the operating meansof said doors.

- 2 In a-submarine a plurality of safety compartments, the inner wallsof which are provided with a plurality of bars spaced away a shortdistance from the walls.
